Which one is more interesting?

[slow briar]

or what is i should change?

[severe harbor]

Right

[spring copper]

The left one is probably the stronger one overall as it's cheap enough to use in an aggro deck as a clean way to punch through big guards and what not. THe downside can be an issue but I wouldn't be suprised if soviet aggro (should it become a thing) would benefit from a card like that. Although it would need to be like fast heinz level of tanks in a deck to not blank

The right side is an entirely different beat and is more so leaning on like big tanks to be useful. It would benefit more in a control shell that can like make more mid to large tanks. It's awkward to use though because it can be so dead early on. It would probably need to be cheaper or have some basic effect alongside the current one to be useable

I feel like it is less efficient Target Acquired

Especially if you gonna use it in aggro

[cunning quest]

what do you mean by "stat"?

i recommend this: if you control a tank, destroy a unit with the same cost as a friendy tank

inconsistent but cheap at 2k

[slow briar]

stat is attack+defense

[cunning quest]

ok

maybe you should specify because afaik that's not a term used in kards

[versed bramble]

I feel like the left matches the theme better, although in both cases I think you will have to be more specific than highest/lowest "stat."

Cost perhaps? Since it is ramming, maybe defense?

Oh, nm

Attack + defense is an interesting idea for making "stat" a keyword. Still, I feel like only defense need apply here
